SPECIFICATION forming part of Letters Patent No. 539,628, dated May 21,1895. Application filed November 20,1894. Serial No- 393- (No model.)

To all whom it may concern: 7

Be it known that I, FREDERICK MAYER, of the city of Baltimore and Stateof Maryland, have invented certain Improvements in Apparatus forManipulating the Lids of Purifier- Boxes in Gas-Works, of which thefollowing is a specification.

In the description of the said invention which follows, reference ismade to the accompanying drawings, forming a part hereof, in whichFigure l is a transverse section of a purifier-house, together with itscontents, which include the apparatus embodying the present invention.Fig. 2 is a longitudinal sectional view of a part of the purifier-house,together with a portion of the apparatus shown in Fig. 1. Fig. 3 is anenlarged plan view of the raising and shifting apparatus alone. Fig. 4is a still enlarged sectional view of a carriage and purifier-lid, shownin Fig. 2. Fig. 5 is an enlarged view of parts of Fig. 3, and Fig. 6 anend view of Fig. 5.

Referring now to the drawings, A is the purifier house and B B are thepurifier boxes. 0 O are the lids of the said boxes, which have to beraised and shifted in position.

D. D are track rails consisting of I bars which extend longitudinally ofthe house A.

These track rails are supported by other I bars E, which project fromthe side walls a of the building, and also by rods b pendent from theroof truss.

F is a carriage on the rails D, adapted to be moved longitudinallythereof. The ca rriage is formed of bars 0 which united constitute thecarriage frame and it has truck wheels 62 and 01 which sustain it on thetrack rails. The truck wheels (1 are secured to the shaft 6 which isrevolved to move the carriage longitudinally of the track rails D. Theother truck wheels are idlers and merely support the carriage.

G and G are spindles one at each end of the carriage, provided with aright-hand threadf at one end, and a left hand thread 9 at the other, asshown particularly in Fig. 3. On each threaded portion of the spindlesis a nut it having eye-bolts j to which chains is are fastened. Thesechains lead over pulleys m and may be attached to the lid 0 of apurifier box B. From this it will be seen that a lid may.

be raised by turning the spindles in one direction and lowered by areverse turning.

H is a shaft having a rope sheave n and a pinion 0.. This pinion is inengagement with a gear wheel 10 ona shaft g which shaft carries a pinion7' in mesh with a gear Wheel 8 on a shaft 25. I is another shaft drivenfrom the shaft 25 by means of gears u andv which are of equal size. Theshaft I carries two sprocket wheels (1, and b. The sprocket wheel b isconnected to a similar sprocket wheel 0 which isloose on the plain orunthreaded portion of the spindle G, by means of a chain belt d. On thesaid spindle is a similar tight sprocket e which is connected to asimilar sprocket f which is tight on the. other threaded spindle G, byachainbelt g. The shaft 25 has also a sprocket wheel h, larger than theone b on the shaft I, and it is connected by a chain belt to a sprocketwheel 2' which corresponds in size with the one a. The said shaft 25 hasalso another sprocket Wheel j about the same diameter as the one a onthe shaft I. The sprocket 3" drives, by means of a chain belt m, a loosesprocket wheel is on the shaft 8 to which the driving truck wheels 01are fastened.

The sprocket wheel a before alluded to, drives, by means of a chain beltn, a loose sprocket 0' on the shaft 6.

A double faced sliding clutch member p is fastened to the spindle G, andthe loose sprockets c and 'i have clutch teeth on their opposing faces.thus be made to engage with either sprocket by moving it longitudinallyof the spindle. When the clutch member 10 is brought into engagementwith the teeth of the sprocket wheel 0' the spindle is turned 'in thedirection required to bring toward each other, the nuts h, and thechainsk being tightened, the purifier box lid 0 to which they areattached, is elevated; but when the said clutch member p is made tointerlock with the teeth of the sprocket 2" and leaves the one a, thedirection of revolution of the spindle G is reversed and the lidlowered, and the lid is lowered faster than it was raised, in view ofthe sprocket it being larger than the one I). Another double facedsliding clutch member The clutch member can q tight on the shaft e maybe interlocked with eitherof the loose sprockets 7a or 0, the saidsprockets having teeth similar to the ones on the clutch. By thisgearing, the lids of the purifier boxes may be either raised or lowered,and the raised lid which is suspended from the carriage movedlongitudinally of the building.

To give movement to the shaft H, a main driving shaft J which is at oneend ofthe building, and receives its motion from any source, is providedwith a rope pulley K. A similar pulley L on a shaft M at the other endof the building is connected to the pulley K by an endless rope N. Inorder that the rope N may be always tight, and have a uniform tension,the upper section of the rope runs around the sheaves O andP the latterbeing.

suspended by a weighted cord Q which runs over the small pulleys R. Thelower section of the endless rope N passes over pulleys S S shown inFig. 3 on the carriage F, and under the sheave 7?. which is on the shaftH having the first gear wheel of the train described. Now it will beseen that by moving the endless ropeN the train of gearing described isset in motion, and when the clutch q is brought into engagement witheither of the sprockets k or o, the carriage is moved longitudinally ofthe track rails and of the building. The clutch member g has a shiftinglever a fulcrumed at b to the carriage, and at its outer end is providedwith eyes 0 to which rods and chains e are attached. These rods andchains are connected at the other end to a T hand lever f pivoted at 9and provided with a guide 712. The said hand lever and the guide haveholes 73 through which a pin j may be inserted to hold the hand lever inany one of its three positions. By moving the handle f 2 the clutchmember q may be brought into engagement with either of the sprockets 7aor 0 and the carriage thereby made to traverse the track rails D ineither direction. The clutch member 19' has a lever fulcrumed at m to apart of the carriage, having eyes n which are united to a T hand lever 0by means of rods and chains 19 The operation of this hand lever is thesame as the one f except that it moves a difierent clutch member and onewhich may be connected to either of the sprocket wheels 0 or i on thespindle G. By this arrangement the chains 70 are practically lengthenedand shortened so as to lower or elevate a purifier box lid when attachedthereto as shown particularly in Fig. 4.

When the lid of a purifier box is to be raised and then carried awayfrom the box so that the same may be, filled, or emptied of itscontents, the hand lever 0 is moved in the direction indicated by thearrow and held in the new position until the ends of the chains 70 canbe coupled to the box lid. The said hand lever is then moved to theother extreme position which efiects the elevation of the lid and thiselevation continued until the lid is raised to the desired height. Thehand lever is then placed in a central position which disconnects theclutch operated by it from both adjacent sprocket wheels, and themovement of the spindle is stopped. The hand lever f is then moved insuch direction as will efiiect' the transportation of the lid to thedesired part of the building and when this place is reached, the lid maybe either left suspended or lowered, as required. To stop thelongitudinal movement of the carriage the lever f is placed in a centralposition.

After the box has been filled with new ma terial the operation describedis reversed by a proper manipulation of the hand levers.

It will be understood that the rope N produces all the operationsdescribed in connection with the purifier box lid by merely moving thehand levers as described.

I claim as my invention- In an apparatus for raising, lowering andshifting the lids of purifier boxes in gas works, the combination of anoverhead track, a carriage adapted to traverse the track, a pair ofrevoluble spindles supported by the carriage, each spindle having aright hand thread at one end and a left hand thread at the other, a nuton each threaded portion of the spindles having hoisting chains adaptedfor attachment to a purifier lid, gearing to effect a joint movement ofthe two spindles in either direction of revolution, to lift or lower thepurifier box lid, other gearing to effect the movement of the carriagelongitudinally of the overhead track, and an endless moving rope to givemotion to the said gearing, substantially as specified.
